FRANK JONES, OF SALT LAKE CITY, UTAH.

BEET SCREENING, FILING, AND LOADING MACHINE.

Application filed August 19, 1919.

To all whom it may concern.-

Be it known that I, FRANK Jones, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in BeetScreening, Piling, and Loading Machines, of which the following is aspecification.

My invention relates to certain new and useful improvements in combinedmachines having means for receiving beets, or material to be handledfrom a wagon or other conveyance; means for screening out or separatingthe dirt or other foreign matter from the beets and determining theamount of said dirt; and means for subsequently piling the clean beets,or material and loading the same onto a conveyance, or depositing thecleaned material at a point of de posit.

A leading object of the present invention is to construct a machine ofthe type mentioned having instrumentalities for carrying out the severaloperations in a rapid, continuous and satisfactory manner, and with thisend and other objects in View my invention consists of the parts and theconstruc tions, arrangements and combinations of parts as I willhereinafter describe and point out in the appended claims.

A further object of my invention is to construct a single, compact,portable machine of the tractor type, having means for receiving beetsor other material directly and from conveyance on the ground, and afterweighing. The gross contents of the conveyance is elevated and screenedand the dirt from the beets dumped is returned to the conveyance and itsamount determined, while the cleaned beets are elevated and conveyed toa pile or to cars, said machine being equipped with the necessarymechanical parts for propelling the machine over the ground and foractuating the conveying and other mechanisms, as I will hereinafterdescribe.

Til the accompanying drawings forming part of this specification andwherein similar reference characters indicate like parts in the severalviews:

Figure 1 is an end elevation of a combined loading andunloading machineembodying my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a top plan view showing the trommel or screen and portions ofthe conveyers broken away.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Serial No. 818,453.

While the machine I am about to describe in more or less detail will befound useful in the handling, screening and storing of different kindsof material, I have designed it primarily to operate upon sugar or otherbeets; in other words for the purpose of dumping the beets from aconveyance, located on the ground, into a series of hoppers which feedthe beets to appropriate conveyors, which latter are designed to elevatethe beets and the associated dirt and other foreign material, to arelatively flat conveyor which transports the beets and dumps them intoa trommel, or rotary cylindrical screen. During the conveying operationthrough this screen, the dirt which is associated with the beets isscreened out or separated from the beets and the separated dirt orforeign material, is conveyed to a hopper having, if desired, acontrolling discharge gate or valve.

The cleaned beets from the trommel are designed to be elevated to a pileor loaded into cars by means of a suit-able conveyer.

In said drawings, I have illustrated in Fig. 1, a conveyance which maybe of any suitable character, the body a, thereof being shown in itsdumping posit-ion. From the conveyance a the beets or other materialdrop into a series of hoppers herein shown as three in number t) theconveyance being tilted a little at a time to properly feed the beets sothat they will not spill. over the sides of the conveyer with which thehoppe s communicate; this tilting of the conveyance may be effected byany suitable means and for this Urposo t have shown a, pair of pullewblocm c, attached to a or no (Z of suitable construction, as shown inFig. and a lli? ling-l ne which is rove throumi the pulleys and has itsfree end suitably connected to a winch or winding drum, f, on atransverse shaft m. To operate this shaft, a chain drive may be employedand to this end I show a chain running from the upper sprocket wheel dotthe tail pulley of the horizontal or flat conveyer, 71, which I willhereinafter describe, to a lowe sprocket wheel j, on the shaft of whichis a worm k, which engages a worm-wheel Z on the shaft m, said shaft andwinch carrying the members of a suitable clutch a, which controls themotion of the winch. Any desired accessories of the usual type may beemployed in connection with these features.

From the hoppers, b, the beets dropped thereinto from the conveyance afall upon Cir under the hoppers b. This main frame is hinged at thepoints, Z, (Fig. 2) so as to be detachable and the two parts madereadily portable.

The conveyer frames before described are hung to the main frame H byangle irons or equivalent structures.

The frame of the trough conveyer, p, is of any desired construction andis hinged to the main frame at the points, Y, and is supported near oneend by the wheels, 0 and is detachable at the hinges Y, so that it canreadily be separated for transportation purposes. The hopper and headpulley of this trough conveyer are also suitably supported. Suitablesupporting agencies are also provided for the flat conveyer, h. Thetrommel or'rotary cylindrical screen, (Z is supported by beams runninglengthwise and cross-wise; the lengthwise extending beams are hinged atthe lower end P. to the main frame of the machine while the other andupper end of the trommel is connected to the elevating screw (0. beforedescribed.

The frame of the trough conveyer, f, is of suitable construction and issupported by the main frame, which also supports a cantaliver frame, Q2) to which the upper part of the conveyer frame is attached. The twoidlers, B (Fig. 2) which carry the chain drive for the trough conveyerare supported on the main frame by a channel iron or other support, R

From the foregoing description it will be understood that the machineshown has the necessary equipment to dump and receive the contents of aconveyance and to convey and elevate the same, and separate the dirtfrom the beets; that the oversize, represented by the cleaned beets isconveyed and elevated into a suitable receiver, and that the undersizefrom the screen representing the dirt, is caught by a conveyer anddelivered into a hopper and finally sent back into the conveyance fromwhich the beets were originally received, and its amount quicklyascertained.

The machine carries its own motive power and the entire operation iscontinuous. The machine is portable and flexible and can be moved fromplace to place so that it will pile beets, or other material. into anysize pilethat a given area will permit; it can also be drawn alongside astring of cars and load them without the necessity of moving the cars.
